Irrigation Well Pump Stop Working After Breaker Jumped - Please Help.

Hi All,
My sister bought this house that came complete with well irrigation system; everything works fine until last week. I don't know much about well irrigation system, so please forgive me if I sound un-educated in this field. As the title stated, the irrigation system stop working after the breaker jumped. It rained for couple of days straight and the ground was really wet. The breaker for the switch valve jumped; I turned it back on but it jumped again so I just turn it off and let everything dry out before attempting the investigation.
I looked over the system today and this is what I have...

My question is, does the switch ever go bad? I did some search on the site and found sticky showing a switch valve with a switch on the side indicates "auto, on and off" and as you can see mine, does not have a manual level switch.

I know the pressure gauge should be replaced because I can't read it at all; if I am to replace the pressure gauge, what range of psi read out should I get? I think the pressure is reading "0" at the moment.

By the looks of thing, I don't think there's any pressure in the tank either. How do I pressurize the tank again? I have a compressor, can I use it to pressurize the tank again? If so, what pressure should I inject in to the tank?

As mentioned earlier, I have no knowledge in this field so any suggestions are greatly appreciated.

a breaker does not jump, it trips. You have an overload situation, most likely the submersible pump is bad and needs to come out of the well and be replaced. You can presurize the tank but since the breaker trips a soon as you turn it on its not going to help.

Thanks bcpumpguy... Breakers trips, now I know...
Now that everything is drying out, I turned the breaker back on; it does not trips. Also, when I plugged in the switch valve nothing seems to be happening (clicking sound). This leads me to guess the switch might be bad and need replacement. There are sand and dirt inside the switch valve, I'll use the compressor to clean it first and see if this help. Pump removal is my biggest fear!!! Any idea how much one of this cost (rough estimate)? I have to look on how to remove the pump, the metal cover plate on top of the well is rusted pretty bad. The plate comes in two hafts and I think there used to be some bolts (4) on top, but it rusted out as well.
Thanks again for the feed back...

WHOA!!!!!!! Some of those well seals are have 4 pieces of steel with a rubber disc that expands when those bolts/nuts are tightened. Taking those bolts/nuts off can allow 2 of those pieces to fall into the well and trap the pump.

It sounds as though you have a short someplace. Shut the breakers off & check for shorts and continuity on the lines from the breakers to the top of the well and then from the top of the well down to the pump to determine where your problem is. Checking the resistance through the windings and a check of the start & running amps with an amprobe would help in determining the condition of the pump and motor as well.

I have never liked seeing a pressure switch out in the weather, see if you can relocate it inside to keep it from getting wet. Also bugs are known to get into them and prevent them from working properly.

craigpump, thank-you for the response.
If I were to remove the pump, I only way I can do this is to cut the 4" PVC casing; the 4 bolts holding the cover plate as you explained are gone. The head on those bolts completely rusted out.

More info on the electrical wiring...

1. From the breaker box, the breaker is labeled "water softener", but there is no water softener in this location. The water softener outlet is rated for 230v and the line is fine, no short there.

2. The pressure switch is 40/60 square D

3. This is the tricky part (for me); when power is supplied to the pressure switch; I checked wire connections at the pump and this is what I found:
A. Black wire is hot
B. Grey wire is also hot
C. Ground is fine.

The above finding does not sit well with me; again, this may confirm I need a new pump. I have a multimeter, yet I don't know how to use it. I got a GreenLee multimeter kit and thus far I've only used the wand and the outlet tester. YouTube....

I'm with you concerning switches out in the weather, I'll be looking for fake rock to cover it up.
I left the break in the off position since we having more rain this week and looks like it will be the same for next week.

I hate to see anyone spend money on a pump without knowing for sure that is the problem. I think it would be worth the money to have a qualified pump installer (not a plumber) come over and trouble shoot the system for you. You may find that a splice in the wire downhole has failed or there is a chaffed spot in the wire.

As for brands of pumps, I have been installing Frankin pumps & motors almost exclusively for several years with no complaints. I would NEVER install something from a big box store or from a farm supply place. Stay with a pump that uses stainless steel motor mounts and discharge heads and comes with at least a one yr warranty. Better yet, talk to the pump installer who you get to troubleshoot your problem, most of us offer 5 year warranties on pumps we install. Sure it may cost more, but there is peace of mind knowing that the pump will be covered in the event that it fails.

i agree, most likely short in an underground wire. being as it seems to be worse in wet weather, check the wire from plug to switch (assuming wire from breaker to plug is good) and from the switch to the well head before you start tinkering with the well.

if you do need to get to the pump. cut the line at the well head, twist it a little and you'll know how tight the seal is. carefully see if u can pull it up a little through the well seal. looks to be hung on glued pvc, so maybe its not set all that deep and you'll be able to pull it by hand. many times those bolts on the seal arent super tight anyway. i have dealt with some pretty bad seals. if you can get someone/something to pull up on the pump line, you can likely pry it up with a good strong flat head screwdriver or similar. if you can find a big pipewrench and twist the well seal some, that will help. might not be a huge job, but u know how that goes. wouldnt be crazy to call for help.

just noticed i have a motorcycle as my avatar.. not sure where that came from

I checked the continuity from the plug head to the PS, all wires are fine. I then checked the continuity for the wires going from the PS to the pump and all the wires are fine. While I was at the PS, I poked around and saw these... There seems to be some sort of built up on the faces of the contacts; is this normal? Can I clean it out or replace the PS? I know this may not solve my problem, but I have to take one step at a time.

Thanks, I'll replace it... Also I looked on Well-X-Trol website, their tank is pre-pressurized @ 38 psi, I checked my tank and it read 20 psi; again, is this normal? Do I need to add pressure and bring it back up to 38 psi? My tank is rated 125 max psi.

Yeah 38 PSI air is correct for a 40/60 pressure switch. Points burned like that is the first indication of too much cycling on and off. Cycling causes you to need the replace the pressure switch a time or two, then it takes out the bladder in the tank and the pump/motor next.

I replaced PS, flipped the breaker and it tripped immediate. Called local irrigation guy in the area; he checked everything I've already checked. Pulled the pump and its burnt. I need new pump, wiring, piping and fitting. The pump was sitting at 80' +/-... Total price tag is $1000.00,he said with my help he can do it for $800.00. Parts alone would cost him around $500.00. Thoughts?

To the best of my knowledge, this is the P&ID for the well system. From cyclestopvalve.com web site, discharge (sprinkler header) should be after the pressure tank? If you look at the first set of photos, you'll notice one line go to the tank.
Here are some photos of the pump.
To replace the pump, can I replace the motor or does this comes as one unit.
I would like to add CSV to the system but not sure where it should go and if I need to relocate the sprinkler header after the tank.
